Alloy and method for producing the same

DETAILED DESCRIPTION I claim: 1.
An alloy comprising: copper, aluminum and Indium; the aluminum ranging between 0.
5% to 7.
5% by weight of the alloy and the Indium ranging between 1% and 5% by weight of the alloy; and the copper ranging in an amount to equal the remaining percentage by weight of the alloy weighing 100%.
2.
An alloy method comprising: the alloying of copper, aluminum and Indium comprising aluminum ranging between 0.
5% to 7.
5% by weight of the alloy and the Indium ranging between 1% and 5% by weight of the alloy and the copper ranging in an amount equal to the remaining percentage by weight of the alloy weighing 100%; wherein the method comprises first heating the copper to a molten state and adding the Indium and the aluminum to the molten copper.
3.
The invention as defined in claim 2, wherein: phosphorus rich copper is first added to the molten copper then Indium is added to the molten copper and then aluminum is added to the copper and Indium melt until the aluminum is melted into the molten copper and Indium.
4.
The invention as defined in claim 3, wherein: the Indium is first added to the melt and then the phosphorus rich copper is added to the melt and thereafter causes a deoxidizing action in the melt for substantially thirty seconds or more.




Description:
BACKGROUND OF THE INVENTION Utilization of aluminum bronzes as a gold substitute has never become widespread in the ornamental and jewelry industry or in related products because of the difficulties of casting such bronzes due to the tendency of such alloys to cast into a generally woody grain structure.
Surface treatment of such castings has previously comprised mechanical abrasion since such prior art alloys are generally immune to chemical pickling or processing fluids.
With such alloys it has been difficult to solder or fuse the various fixtures thereto.
Prior art methods utilizing such aluminum bronzes have resorted to the inclusion of varying amounts of iron, nickel, silicon, manganese, tin, zinc, tellurium, lead and other materials in these alloys in order to render them capable of being readily cast
